I find this supremely rich considering OpenJDK is 100% Oracle and not under the wing of any foundation. So much for open governance. Of course OpenJDK as an internal Oracle project has some hybrid imaginary "board" where Oracle has 2 of the 5 seats by default and you need 4 votes to veto something (which means, no dice without Oracle).
IBM of all should be used to fork projects just to control the pace and trademark. See the recent GraalVM fork (made by RedHat).
